8.5.1.4. Comments on Regime Equations The regime equations have been empirically derived using data of regime channels. These channels carried relatively less sediment load (approximately 500ppm). Thus, the equations can be expected to yield meaningful results only for the conditions in which the sediment load is of the same order as was being carried by the channels whose data have been used in obtaining the regime relations. The dimensions of a stable channel will be affected by the water discharge, the sediment characteristics and the amount of sediment load in the channel. The regime relations take into account only the water discharge and the sediment size but do not take into account the amount of sediment material being transported by the channels. Nevertheless, the regime equations do provide useful information which is very helpful in the design of unlined channels and other structures on alluvial rivers.
